arm: fix incorrect monitor protection region in FLASH

2011-03-27T17:18:52Z

Monitor protection region in FLASH did not cover .rel.dyn and .dynsym sections, because it uses __bss_start to compute monitor_flash_len. Use _end instead. Add _end to linker scripts for end of u-boot image Add _end_ofs to all the start.S. Signed-off-by: Po-Yu Chuang

rename _end to __bss_end__

2011-03-27T17:18:37Z

Currently, _end is used for end of BSS section. We want _end to mean end of u-boot image, so we rename _end to __bss_end__ first. Signed-off-by: Po-Yu Chuang

arm: fixloop(): do not use r8 for relocation

2010-12-09T10:01:15Z

r8 is used for global_data and should therefore be left alone! For C code the compiler flag --fixed-r8 does the job, but in assembler we need to be aware of that fact. Signed-off-by: Andreas Bie�mann

arm: relocate_code(): do not set register useless

2010-12-09T10:01:15Z

In case we are still at relocation target address before relocation we do not need to load the registers needed for relocation. We should instead skip the whole relocation part and jump over to clear_bss immediately. Signed-off-by: Andreas Bie�mann

arm: copy_loop(): use scratch register

2010-12-09T10:01:14Z

This patch uses r1 as scratch register for copy_loop(). Therefore we do not longer need r7 for the storage of relocate_code()'s 'addr_moni' (the destination address of relocation). Therefore r7 can be used later on for other purposes. Signed-off-by: Andreas Bie�mann

Switch from archive libraries to partial linking

2010-11-17T20:02:18Z

Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier

ARM: fix linker file for newer ld support

2010-11-17T19:44:32Z

older ld emitted all ELF relocations in input sections named .rel.dyn, whereas newer ld uses names of the form .rel*. The linker script only collected .rel.dyn input sections. Rewrite to collect all .rel* input sections. Signed-off-by: Albert Aribaud
